6 Claims. 1

The present invention relates to wall lamps and is more particularly directed toward wall lamps adapted to be secured to the wall without requiring any interior, wall-carried wiring.

The present invention contemplates -a wall lamp which is made up in the form of two separable units, one carrying the lamp socket, lamp bulb and structural parts whereby it may be secured to screws, hooks or the like carried by the wall, the other part including a shade frame and shade, all detachably secured to the first part. The fixed unit carrying the lamp bulb is also provided with a reflector which intercepts upwardly directed light in regions where it would otherwise fall on the adjacent wall surface, thereby avoiding a bright, or hot, spct immediately above the wall lamp.

According to the present invention the shade is arranged so as to obscure the lamp bulb in all ordinary directions of observation. It, however,

allows a small amount of light to escape upwardly for subdued ceiling illumination and the escape of a substantial amount of light downwardly and outwardly away from the wall for illuminating a work area below.

Other and further objects will appear as the description proceeds.

For purposes of illustrating the present invention the drawings show an embodiment in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figure 1 is a perspective view of the wall lamp from underneath the lamp and taken from the room side;

Figure 2 is a perspective view of the Wall lamp taken from below the lamp and showing it de tached from the wall;

Figure 3 is a vertical sectional view on the line 3-3 of Figure 2;

Figure 4 is a top plan view of the lamp with parts broken away;

Figure 5 is a fragmentary section on the line 5-5 of Figure 3; and

Figure 6 is a perspective view showing the assembled lamp from above.

The wall of the room is indicated at W. As shown here the wall carries a suitable support such as two screws [0, l by which the wall lamp is secured in place. All parts of the wall lamp are carried by a metal strap I2 having slots [3, I3 or other convenient means whereby the strap may be engaged with the supports Ill. The lower end of the strap I2 is bent forwardly as indicated at M and obliquely downward as indicated at IS. A lamp socket It and switch I! are secured to the front portion l of the strap. The socket [6 extends obliquely upwardly and carries an incandescent lamp bulb I8. The current supply cord IQ for the lamp socket extends through an insulating sleeve carried by the strap [2. A light deflector 2! is secured to the strap l2 in any suitable manner, as for example by rivets indicated at 22. This deflector is above the lamp bulb and is shaped to intercept a large solid angle of upwardly emitted light so as to screen a relatively high, wide region of the wall surface immediately above the wall lamp and to the sides of the wall lamp, thereby preventing direct light from the bulb falling on these regions of the wall. The upper end of the strap I 2 is bent forwardly as indicated at 23 and drilled at 24 to receive a screw 25. As shown, a screw passes through a nut 26 and extends upwardly as indicated at 27.

The shade-forming unit has a wire frame provided with a top bar 34] which carries an apertured fitting 3! adapted to be placed about the upwardly extending screw and rest on the nut 26. The outer ends of the upper bar 30 are connected by a horizontal, bowed wire element 32 and the ends of the bar 30 are connected to downwardly extending frame members 33, 33. These members usually diverge and their lower ends are connected to a horizontal frame member 34 looped as indicated at 35, Figure 5, and to a horizontal forwardly bowed frame member 36. The frame made up of the parts 3| to 36 inclusive forms a self-supporting structure which can be attached to or detached from the wall carried strap I2 without in any way interfering with the wiring or the lamp bulb. The members 30, 33 and 34 form a trapezoidal frame adapted to rest against the wall, and the members 32, 33 and 36 support a generally frusto-conical shaped piece of shade material 31. This form of shade and shade frame resembles one-half of the ordinary annular shade used on a floor lamp.

The upper member 32 is somewhat larger than the reflector 2| so that some of the upwardly directed light may escape as indicated at 38 between the refiector 2| and the shade so as to provide subdued ceiling illumination. The lower part of the shade 31 may be left open so that the direct light is transmitted without interference and the interior parts of the wall lamp are unobscured or it may be closed by a highly translucent sheet as indicated at 40 notched at 4! to accommodate the socket support. This sheet affords some diffusion of light downwardly, reduces harsh shadows and obscures the interior parts. The shade frame may be held in position by an ordinary finial 42 threaded onto the bolt 25.

Wall lamps such as contemplated by the present invention may be installed by the purchaser without having to make any provision for wiring in the wall, the lamp cord being plugged into a suitable convenient outlet. The unit may be open at the back or may, if desired, be closed off by a protective sheet 43 which protects the wall and affords improved reflection over what might be available if the wall surface were too highly light absorbing.

Since it is obvious that the invention may be embodied in other forms and constructions within the scope of the claims, I wish it to be understood that the particular forms shown are but a, few of these forms, and various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.

What is claimed is:

1. A wall lighting fixture comprising two separable units, the first unit including a relatively narrow, vertically extending back strap having means to secure it to a wall, an upwardly extending lamp socket and incandescent lamp bulb in front of the strap and supported from the bottom of the strap, the second unit being detachable from the first and including a shade having a vertical rear frame adjacent the wall with side portions spaced laterally from the strap and top and bottom frame members extending forwardly from the upper and lower ends of the rear frame side portions and wall above and below the lamp bulb, and screening material carried by the side portions of the rear frame and by the top and bottom frame members to shield the lamp bulb.

2. A lighting fixture such as claimed in claim 1, having a current supply cord extending downwardly from the socket, and wherein the lower member of the shade frame has a rearwardly opening loop through which the current supply cord extends.

3. A lighting fixture such as claimed in claim 1 having a light shield secured to the strap and extending forwardly from the strap, the shield being wider than the bulb and intercepting up- 4 wardly and rearwardly emitted light to prevent its falling on the wall above the fixture and for reflecting light downwardly.

4. A lighting fixture such as claimed in claim 3, wherein the top frame member extends forwardly of the light shield and is open to allow light to escape forwardly of the shield and toward the ceiling.

5. A lighting fixture such as claimed in claim 1, wherein the lamp socket is secured to a lower forwardly bent portion of the strap and the shade frame is secured to an upper forwardly bent portion of the strap.

6. A wall bracket type, portable lamp, comprising a relatively narrow, vertically extending back strap having means to secure it to a wall of a room, an upwardly opening, lamp socket secured to the bottom of the strap, an incandescent lamp bulb in the socket with the filament spaced forwardly of the strap and between the upper and lower ends of the strap, a light deflector secured to the strap and extending forwardly of the strap above the lamp bulb the deflector being wider than the bulb and intercepting light which would otherwise be transmitted upwardly to meet the wall and reflects light downwardly, a combined shade frame and shade occupying one side of an upwardly tapering generally frusto-conical region to the front of the strap, the lamp and deflector, and of a height substantially the height of the strap, the frame and shade having a top opening larger than the deflector through which light forward of the deflector escapes, and means to secure the shade frame to the strap.
